To briefly explain my problem, when I play the audio track on Audacity and any media player on my PC, it sounds absolutely perfect. When I try on my phone's media player, it also sounds perfect. But when I implement in a games files as a soundtrack, it sounds HORRIBLE. Lowering the project rate hz reduces the hiss sound, but the sound quality reduces aswell. I have tried: Equalizing. Low pass filtering. Db volume lowering. Changing frequenzy rate and resampling rate. Noise reduction didnt work also (probably cause Audacity and other media players dont detect that hiss sound).
NONE OF THE ABOVE HAVE WORKED FOR ME.
PS The track I am trying to fix is downloaded music.
